ANDREW GOOD, or LOS PATENT OFFICE ANGELEB, CALIFORNIA SLUG-CAS'IINGTYPESETTING-MAGHINE OPERATION Application file d July 14,

This invention relates to improvements in linotype machines and moreparticularly to means for operating the keys thereof and has for itsobject to provide a simple, eflicient and inexpensive device ofthischaracter.

Another object of this inventionis to provide improved mechanism in alinotype machine for replacing the conventional linotype key-board bymeans of a standard typewriter keyboard.

' Another object of this invention is to provide means in a linotypemachine for adapting the present linotype keys to a standard typewriterarrangement of keys.

' A further object of this invention is to provide a keyboard as anauxiliary or supplementary attachment to the present style of linotypekey-board for the purpose of dispensing with special skill in theoperation of the linotype machine.

A further object of this invention is to provide means for removablymounting the auxiliary key-board upon the key-board of a conventionallinotype machine.

A still-further object of this invention is to provide mechanismmagnetically controlled for manually operating the keys of a standardlinoty e machine thru the medium of auxiliary keys.

Another object of this invention is to provide shift keys on. theauxiliary key-board with an arrangement for translating the action ofthe shift keys into operation of the proper keys on the linotypemachine.

Another object of this invention is to provide mechanical key pushersfor operating the keys of the linotype machine, said key pushers beingmagnetically and electrically controlled.

With the above and otherobjects in view my invention consists in thecombination, arrangement and details of construction disclosed in thedrawings and specifications, and then moreparticularly pointed out intheappended claims.

Referring to the drawings which are merely illustratlve of my inventiona base board or key board is designated 10 having an inclination whenapplied upon the keyboard of a linotype machine. One of the hangers '11for this key-board is shown in Figure 3, being designated 11' and theangular In 13 thereof is secured by rivets 12 to the ase board 10-byreason of which the vertically disposed hanger 11 holds the baseboard ininclined position, the lower rightangular por- -tion 14 of this ban erbeing operatively secured to part of the inotype frame.

,A prop 16, is attached in operative manner to the other end of the baseboard 10 and is vertically disposed; two such props may be employed oneither-side of the baseboard, the lower ends of which are respectivelyformed with'the recesses 17 in which is disposed the assembling elevatorlift rod 01' the linotype machine so that this rod 15 serves to supportthe lower front part of the baseboard 10.

In this manner the frame or baseboard 10 is caused to be supported insurmounted position directly over the key board of the linotype machine,the keys of the latter being desgra'mmatic View of the cirand mounted inthis manner it willbe seen that same can be removed at any time. It willbe understood that linotype machines will be built so as to eliminatethe present keyboards found on them in favor of the improved key boardforming the subject-matter of this invention. v A plurality of keys 18are provided for deressible action upon the key board or base om'd 10,and these keys vfollow the exact .40 chine which 'it is designed tooperate; The

order and disposition of the usual keys of the standard typesoftypewriters so that; typists accustomed to handling and operatingtypewriters or the like may instinctively operj concordance between thelinotype and Istandard typewriters being brought aboutby my invention.The'keys 18 are securely mounted upon the extreme outer ends of leafspring rangement of thespring arms 19 is such that they normally supportthe keys in a horiz'on-' tal plane. a

Besides the keys 18 devotedt'o the-usual letters andnumbers andpunctuation marks shown in Figure 1 there are the usualtype writershiftkey lever having the key 20 and the latching key 21 therefor. A seriesof electro-magnets'25 are provided, one for each particular key of theseries of keys on thekeyboard; each magnet 25 isstrungsecurely upontheu'nder side of the board 10 by a fastener of suitable construction 24secured into this board and serving to position securel the rightangularportion 26' of a hanger 2 made of strap iron or'th'e like whose lowerportiorr28 serves as a fulcrum bearing for'a key-pusher or depressor 29.Each depressor consists'of the armature end 31 arranged normally inspaced but contiguous relation with respect to the magnet 25 andthedownwardly.

curved spring metal finger 32 terminating in the curved key-engaging toe33. This depres sor 29 is lever shaped being pivoted centrally upon thehanger portion 28. The toe 33 of each depressor 39 may, if desired, restupon the adjacent key 34 of the linotype mamagnets are thus securedinsulatedlyso as t'o unit.

hang from the base board 10 so that whenthe baseboard is removed themagnets and other parts of my invention are removed as one The shift keyarrangement described as f follows. The'shift-key 20 is secured upon a.bell crank lever whose vertically disposed bell-crank lever and shiftkey device is a push arm 52 carries the key'proper, and whose remainingarm 47 is designed to'make electrical contact in its arcua'te sweep withany of a number ofconta'c'ts, say the three contacts 49 mounted upon thearcuate shaped strap 48 operatively secured upon the under side of theboard 10. Pivoted upon the arm .47 of the rod or bar 38 carrying thelatching key 21,

joint movement, a. p ivot 51, fulcruming the arm 47 upon afixed hanger50' alsoisecu'red 33' is' depressed, thereby depressing the-apto theunder side of the board 10. The base board 10 is formed with a'- slot 42for the -push bar 38to move in another slot 53 being hook 40a of the bar38.

the'pr'oper em or en spaces or of the space band'of the linotypemachine. At each end of each of these. spacer members is a screw pin 57tapped into this member and also secured in the lower base board;alongside- .of this screw pin is another pin screwed into the member 54as at '59., while an alining pin 60 is secured into the base board 10. Aspring These three keys determine the operation of 58 is-coiled. aroundpin .57 which holds the The-electrica1c1rcu1t includes a-magnet each'keyin the series of keys; a switchfor v closing the circuit to the. magnetanda pusher or. equivalent device for releasing the matrices. Referringto Figure 9 it will beseen that a battery or source of electricity'62 isemployed, and from one side of thisbattery runs a wire 64 from whichconnect wires 65, 67139 the contacts 36 of the key board frame 10, thecircuit however being openbetween wires 65, 67 due to the, key 18.beingnormally spaced out of engagement with the fixed. contact 36. Wire67 nunsto the magnet 25;

from whichruns the wire "66 to the wire 63 which runs back to the otherside .of the battery. In the same way the shift keys control magnetswhich operate the key pushers or the matrix-operating selective parts ofthe linotype machine.

In operati the operator familiar with the use and operation of anystandard t pewriterjdepresses the keys 18,- or shift eys 21,, 20v forthe large caps or 20a, 21a for the small caps, andin this manner willcause the matrices of the linotype machine to be 'operated selectivelyand interchangeably as called for by the characters of the text. In

depressingany particular key 18 this key flexes the spring arm 19sufliciently to make the key 18 and the particular contact for switch 18interengage; thereupon the circuit .is closed thru the battery orgenerator 62 to the particular. magnet associated with this gized anddraws to itself the armature end 31 ofthe particularpusher 29, and indrawing this end of'the lever in the curved toe key; thereupon thismagnet 'becomes'enerpropriate linotype key 34 and operating the machine.I

- In this application, and disclosure it should,

proper matrix to cast the proper character printed on the key depressedin the first place; in this connection it will be noted that the magnetmay control the operation of any device designed to operate the propermatrices whether keys 34 be used or not.

When the spacer members 54, 55, and 56 are operated the particular sizeof space required is provided for in the line cast on the slug; and whenoperating the particular shift key say shiftkey 20, in depressing lever52 against the tension of springllb secured to board 10 at one end andto lever 52 at the other end, this lever in turn draws downwardly thelatching lever 38 so its hook 40a will snap automatically, against thetension of the spring 45, into slot 40 of the board 10. thereby lockingthe lever 52 in set position until lever 38 is depressed again torelease shift key 20. Thus the caps, lower case or small caps are cast.I do not limit myself to theexact details of construction disclosedherein but claim all variations falling within the purview of the claimsin a slug casting be borne in mind that in any linotype ma chine,intertype and linograph in use today the keys thereon are multiplied atgreat length and bear no relationship in order and arrangement to thekeys of the standard typewriter. In any such slug casting typesettingmachine many years of practice are required before a linotype operatorattains a proficient rate of speed, whereas typists on standardtypewriters attain very great speeds at the expenditure of a fraction ofthe time and nervous energy occasioned by the linotype operator. Myinvention brings about great simplification and facilitation in thesetting of small capitals on the typesetting machine by providing ashift key to permit the operation of small capitals from the samekeyboard as the one used for lower case and capital letters. This worksan innovation in the operation of linotype machines. Thus any typistaccustomed to speedily operating the standard typewriter may operate thelinotype machine without previous study or practice and with very littlediminution of speed.

It is intended to construct the novel key t board in a slug castinglinotype machine to replace the key-board now found on such machines andthis may be done even by dispensing with keys at allso long as it ispossible to selectively and manually control the operation and intervalsof activity of the a particular matrices which will form the char actersdesired on the slugs cast. Instead of having to reach far out as onpresent makes of typesetting machines to depress desiredkeys the novelkey-board becomes the real key-board of an existing typesetting machineand reduces to small compass the size of the key-board.

What I desire to claim and secure by Letters Patent is 1. An auxiliarylinotype key-board comprising a plurality of spring supported keys, aplurality of magnets associated in staggered relation with said keys, ofthe main linotype keyboard, an electrical circuit in which said magnetsare included, switches controlled by said spring-supported keys, andpivotal.

pushers controlled by said magnets selectively, for depressing thelinotype keys.

2. A device asdescribed consisting of a key chines in standardtypewriter ashion consisting of an auxiliary key-board surmounting thelinotype keys, means attaching said keyboard upon a linotype over thekeys of the latter, linotype key depressors normally restin upon thelinotype keys, magnets interposed between said depressors and the keysof the auxiliary keyboard for energizing said magnets to selectivelycontrol the latter, and circuit closing devices for energizing saidmagnets controlled by said auxiliary board keys selectively.

4. An auxiliary key-board for linotype machines consisting of a base, aplurality of depressible keys and shift keys arranged in standardtypewriter order, springs opposing the depression of said keys,selectively, a-

group of magnets, one associated with each key, means controlled by saidkeys selectivel for energizing said magnets and lever-shaped pushersassociated with said magnets having armatures attracted by said magnetsand linotype key engaging parts to depress the lat- 5. In a device asdescribed the combination of a frame, an arcuate shaped plate,contactpins arranged on said plate having electrical connections to acircuit, a bell crank lever having one arm pivoted so as to actuallysweep across said contact pins selectively, magnets controlled by theseveral contact pins when contacted, a key board having keys fordepressing said lever, a depending arm on-said frame on which said leveris pivoted, a shaft lever pivoted on the mentioned lever armdepressiblefrom above said keyboard and having an intermediate hook, a
